Promote sweating by taking hot baths, hot foot-baths and other heat therapies. Keep the feet warm at all times during sickness and as a preventive measure. Low body temperature decreases resistance to viruses and bacteria, while heat burns up and destroys the virus.

To warm feet, soak them for five to ten minutes in a hot mustard bath. Dissolve I tbsp. mustard powder in 4 cups of hot water.

A hot bath followed by a cold mitten friction rub, two to four times a day, loosens
congestion, improves circulation and strengthens the immune system, speeding
healing from the flu.

To do a cold mitten friction rub, proceed as follows:

Dip a small towel or washcloth into cold (50° to
60°F) water.

Curl one hand into a fist and wrap the cloth around it.

Use your fist to rub
your other arm in a vigorous circular motion, beginning with the fingers and finishing at
the shoulder.

Dip the cloth in the cold water again and repeat. Your skin should be
pink.

Dry your arm with a towel using the same vigorous circular movement.

Repeat the process on your other arm and on your legs, feet, chest and abdomen.
